Yesterday I turned in one of my three Cox Cablecards. I sold the unit and no longer needed it so...a big $2 a month savings.

Anyway, today my Elite started giving me the "Channel not authorized, V58" message, along with a black screen. A reboot fixed the problem, but only for a couple of hours.

I called the 800 number for Cox cablecard activation. I explained to the rep my problem and told him that I had just turned in a CC, the day before. I asked him was it just a coincidence.
He said "I see the problem. The card that you turned in was the number one card of the three". I think that he called it a Lead card. He switched the number three card to number one and it fixed the error instantly.

I have never run into this problem before and I thought that I would pass it on. Honestly, I thought that he just sent a "Hit" to the card, but he said no, he didn't.

I had something weird happen last night. I was watching Dexter and about 1/2 way through I got horrible pixelation and couldn't watch the show. I figured it was a bad capture so I setup a later recording of the same episode. However I wanted to make sure I wasn't having signal problems so I went to live TV where I discovered I couldn't tuner any channels and got the V58 error. I tried rebooting the TA but it didn't help. So finally I just pulled the plug on the TiVo itself. When it rebooted not only were all the channels working again but the pixelation in Dexter was gone and I was able to watch the rest of the episode without issue. So it seems something was actually so messed up it was causing a problem with playback as well as tuning. Never seen anything like that before.

I have had the same thing happen to me with a XL4 several times. I do a soft reboot under the help menu to keep from cutting power from the hardware and it always fixes the problem which makes me believe it is software as the hardware is not powered down.... Also see loosing all channels thread...

Yes, welcome to losing all tuners world brought to you almost exclusively by the TiVo Elite and the "wonderful" Maxlinear tuners. You're a little late to the party though.

I had someing similar happen once a lo time ago, but I didn't really attempt to trouble shoot it, I just immediately pulled the plug without much thought. That time I lost an entire nigs recordings. This time it seemed to record everything they just didn't play right until after the reboot.

Just got Time Warner and put my cable in card. Do I need a tuning adapter or is it optional for my ppv channels and such. Case ive tried getting my channel lineup updated to TW from cablevision and its just not working. Its stuck on Loading info screen (preparing to load). Been this way for hours now

edit got off the phone with the cable card support. they stated I do not need a tuning adapter for the m-card to work and they are correct I now have my regular and HD channels up and running. But she did say that alot of regular channels will not work with out the TA. and I am finding that out as well. Will grab a TA tomorrow morning and do the setup again.

Should I just split the cable from the TA to the tivo? Or is there an easier more efficient way?

Depends on the brand. The Motorola ones are known for having really crappy pass-through ports so they'll typically recommend you split the cable. I think the Cisco ones have an OK pass-through port so you can use that by running cable from wall to TA, then a short cable from TS to TiVo. With both setups you still need a USB cable going from the TA to the TiVo. (some people assume that when using the pass-through port the TiVo can talk to the TA via coax, it can't)

If you can check the coax cable connections at the fios box.
That's where "they" should start...

I've checked them
I've run signal strength on the offending channels on each Tivo(well 5-6 of them). All show normal
Of course, my real cable box does not exhibit any of this.
I had their system rehit each box
I've reset the ONT terminal (Power failed it with battery unconnected)
